TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN HENRY SMITH, of the city and county of Allegheny, in Athe State of Pennsylvania, have invented anew and useful` Improvement for Raising Oils and Burning-Fluids by Pneumatic Iressure; and I do-,hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

The nature of my invention consists in raising oils, burning-duids, and their gases, by pneumatic pressure, and combining with said oil, liuid, and gases, iine'jets of water, inthe manner and for the purpose hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its application and operation, when applied to the boiler-furnace of aship or other vessel `propelled by steam. In the accnmi panying drawings, which form part of my specification- Figure 1 represents a longitudinal section of the hull of a ship providedwith my improvement. Figure 2 represents a transverse section of the same, cut through at the line marked sc.

In the drawings, A represents the hull of the ship, which is provided with anv oil or fluid-compartment, marked R, the deck unf which is provided with a ooncavity marked cv. On the deck u is placed the boilerfurnace n, in the front wall of which are a number of flanged openings, o, through which pass a number of small pipes, h, which are connected to a T-shaped pipe, B, which passes through the deck u down to the bottom of the oil oriiuid-compartment R. Inside of the T-shaped pipe B is placed a small pipe, C, a portion of which is on the outside of the pipe B, and extends up into the concavity in the deck u. That part of the pipe which extends into the concavity :z: of the deck u, is provided with a cup-shaped mouth, e. A pipe marked 2, connected t0 and leading from pipe B downwards through deck u to the concavity x, may be used, when desired, for the purpose' of conveying the gas or vapor of the oil or uid into the pipe B. The pipe 2 should be provided with a suitable valve, for the purpose of regulating the supply of gas, vapor, or air to thepipe B. When the pipe 2 is used, the pipe C may be dispensed with. From the deck S'is a pipe, A,'which passes downward and through the deck u of the oil or uid-compalrtment Amarked R. The pipes f and f', which lead into the oil or Huid-compartment, should be provided with air-pumps or other suitable means for forcing nir down on the oil or fluid, which may be placed in the compartment marked R. All of the pipes which lead into or out from the oil or Huid-compartment R should be provided with suitable valves, 1. m represents the steam-boiler. 5 represents a waterreservoir, provided with apipe, 6, the lower end of which should be so constructed that'it will throw out very -ine jetsof water into the flame near the ends of the branch pipes h. 'The pipe 6 of the water-reservoir 5 should be provided with a valve, for the purpose of regulating the ilow of water, and the force with which the fine jet ci' water is ejected into the flame, caused by the burning of the oil, gas, and air, at the ends of the branch pipes h. 4

The construction and arrangement of the several parts, and the relation that they bear to each other, will be readily seen and understood by the skillful mechanic, by reference to th'e accompanying drawings. I will therefore proceedto describe the operation oi' my improvement, which is as follows:

The oil or burning-fluid is conveyed into thecompartment R by means of the"pipe A' its valve is then closed. I then force air by means of pumps or other device down through the pipes f and f', 'which` will force` the oil or iiuid up through the pipe B, and out through its branches h. The air which is forced down on the oil or fluid will commingle with the gas orvapor of the oil, and thesurplus of this commixture of air and gas or vapor will be forcedthrough the pipes C and 2 into the oil or fluid, as it ascends into the pipe B, and this mixture of oil, gas, and air is ignited at the en ds of the Vbranches h, which, in connection with the air that passes. through the flanged openings o, around the ends of the branches h ofthe pipe B, and the line jets of water which are thrown from pipe 6 in among the ame atthe ends of the branch pipes h, will cause a complete and perfect consumption of the oil, gas, and air, thereby forming an intense heat in the furnace n of the steam-boiler mi i The advantages of this mode of producing an intense heat by meansV of a light and cheap article of lhi'uel, when taken in connection with the means herein-described, for conveying it to the point where it is consumed, are too apparent to require any narration or enumeration.

I wish it understood that I do not confine my invention to any one kind of furnace applied to any onepur-` pose, for it can be used in any case where a strong and intense heat is required. Ilalso wish it clearly underl stood that I do not claim broadly raising Oils or other fluids by pneumatic pressure, for that is old and well known; but,

What I do claim as ot my invention, is-

Raising, by pneumatic pressure, oils or burning-fluids from an oil or iiuid-nompartmont of a. ship or other vessel, and mixing with said oil and fluid the gas generated therefrom, as herein described and setforth.

I nlsoclaim the combination nndarrungement of the pipes A, B, C,f, andf, when used in connection with an Oil or finiti-compartment, R, of a. ship or other vessel, the whole being constructed, arranged, and Operating substantially in the manner herein described and for the purpose set forth.

I also claim, in connection with the above, ejecting,l nejets of Water into the llame, caused by the burning v ofthe oil or iuid and other matter mixed therewith, :is herein described and set forth.
